ghdl --help -a

gives:
 --ieee=NAME    Use NAME as ieee library, where name is:
    standard: standard version (default)
    synopsys, mentor: vendor version (not advised)
    none: do not use a predefined ieee library


But these packages are non-official ieee packages and have numerous
problems, so it's best to convert it to numeric_std.
